Hi,

in Allplan 2024(and older), I used this code to extract profile geometry from a collection of library elements.

def make_profile_area_from_lib(path:str,name:str,
                                   type:AllplanBasisElements.LibraryElementType,
                                   placement_mat:AllplanGeo.Matrix3D,doc):
    """
    Erstellt Profil Polygon aus Bibliothekselement. Mit Polygonisierung.

    Args:
        path: Pfad zum Element
        name: Name des Elements
        type: Type des Elements
        placement_mat: Platzierungsmatrix
        doc: Documentadapter des aktuellen Dokuments

    Returns:
        Polygon3D
    """
    lib_ele_prop = AllplanBasisElements.LibraryElementProperties(path, "",name,type,placement_mat)
    be=AllplanBasisElements.LibraryElement(lib_ele_prop)
    path2d,poly3d=AllplanGeo.Path2D(),AllplanGeo.Polygon3D()
    for geo in be.GetGeometryElements(doc):  
        if isinstance(geo,AllplanGeo.Arc2D):
            err,poly=AllplanGeo.PolygonizeEqually(geo,geo.GetStartPoint(),geo.GetEndPoint(),3)
            path2d+=poly
        else:path2d+=geo
    err,path3d=AllplanGeo.ConvertTo3D(path2d)

In 2025 it`s not working anymore. In 2024, same code with same libraryelements is working fine.
Any ideas? Thank you.
